Microfossils from the Judith River Formation near Hinsdale, Montana, 2023 fieldwork season.

Scientists, led by the UK’s University of Sheffield and Boston College in the USA, discovered a microfossil in the Scottish Highlands, which could be the oldest fossil of its kind on record. The tiny fossil, dated to around one billion years ago, contains two distinctly different cell types and appears...

Not everything that lived at the time of the dinosaurs was big.  In fact, many animals then were micro in size!  Starting directly above Lincoln's head and going clockwise we have a fish tooth, a crocodile tooth, a nearly complete mammal jaw, 3 different species of dinosaur teeth, an amphibian jaw and a stingray tooth.

Pachycephalosaurus front teeth look an awful lot like dromaeosaur teeth! I’d probably be fooled if I found them individually.

More microfossils!! This is my favorite slide so far

“Microfossils found in China have revealed what could be our earliest known ancestor on the tree of life, researchers say. But don't go looking for a resemblance. Saccorhytus, which looks a little like the "chestburster" from "Alien," was a tiny, bag-like sea creature that lived 540 million years ago.”
